In order to ensure flawless and reliable operation, even with larger sprocket cassettes, the precision of forward and reverse shifting has required very extensive research and development work in order to design such a reliable and reliable 12-speed chain. resistant over time, despite a reduced thickness, than an 11-speed chain.

The new 12-speed Chorus group benefits from a new Chorus 12 chain which guarantees the same reliability and the same performance as that of the Super Record level, while it weighs only 241 grams for 110 links.

Details:

Weight: 243g
5.15mm width
Faster shifting
Optimal and long-lasting performance
Axes aligned with outer surface
Fluidity and precision
Same wear resistance
The chain loses weight and becomes thinner but it lasts as long as the 11-speed model
Optimized drawing
Optimal functioning in harmony with the design of the pinion teeth and crowns
Ultra-Link System
Optimal fluidity and reduction of dispersions.
